HYDROCARBON-BURNER.

Application filed September 6, 1912.

To all whom it may concern:

Be it known that I, W'AL'rnR E. HUnNE- Fina), a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Hydrocarbon- Burners; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in hydrocarbon. burners of the type employed in oil stoves,-the object of the invention being to provide simple, cheap and eilicient means for raising and lowering the combustion chamber member relatively to the wick; for sustaining said combustion chamber member temporarily in elevated position, and for locking said combustion chamber member in its lower operative position.

With this object in view the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings Figure 1 is a sectional view showing the positions of the parts in their normal operative relation. Fig. 2 is a similar view showing the combustion chamber member in its elevated posi tion, and Figs. 3 and 4 are detail views.

1 represents a wick tube member comprising concentric tubes 23 forming a wick chamber, closed at its lower end. A wick 4 is located within the wick chamber and provided with a metal perforated holder 5 to be engaged by a toothed wheel 6 mounted on the wick tube member. This toothed wheel is carried by a suitable shaft 7 provided with a hand wheel for operating the same to raise or lower the wick.

The upper ends of the wick tubes are provided with seats 910 for the lower edges of foraminated shells 1112 of the combustion chamber member 13. These shells are arranged, one within the other, so as to form a combustion chamber between them and they are surrounded by a suitable casing 11 (spaced from the outer shell),said casing being provided at its lower end with an inwardly projecting, perforated flange 15. The inner shell of the combustion chamber member may be provided with a perforated Specification of Letters Patent.

cap 16 and at or near the lower end of said inner shell, a perforated cap 17 is provided.

To the lower cap 17 of the combustion chamber member, the upper end of a cylindrical extension 18 is secured. The connection bet-ween the cylindrical extension 18 and the cap 17 may be conveniently effected by means of lugs 19 projecting from said cylindrical extension and passing through slots in the cap 17, the upper ends of said lugs being bent over or upset.

I prefer to make the cylindrical extension of sheet metal and of such size that it will enter the inner wick tube in a manner to form a guide for the vertical movement of the combustion chamber member. At its lower end, the cylindrical extension is made with a plurality of approximately L-shaped notches 20 and the metal under the horizontal portions of said notches is bent inwardly to form a plurality of inwardly pro-- jecting lugs or fingers 21.

A ring 22 is located within the cylindrical space formed by the inner wick tube and is provided with arms 23 rigidly secured in any suitable manner to the interior of said inner wick tube. The ring 22 is made with a plurality of upwardly projecting arms 24; corresponding in number with the notches 20 of the cylindrical extension 18. Each of these arms is provided at one side with a diagonal edge 25 and at the upper end of each diagonal edge, a horizontal seat 26 is formed and at one end of the latter, a lug 27 projects upwardly so as to form a stop shoulder 28. At the side of each arm 24 opposite the diagonal 0r inclined edge thereof, a horizontal slot 29 is formed,-the lower wall of horizontal slot in one arm forming in effect a continuation of the inclined or diagonal edge of the adjacent arm but at an angle to said edge.

When the combustion chamber member is in its normal operative position, the inwardly projecting lugs 21 of the cylindrical extension will be disposed in the horizontal elongated slots 29 of the arms 24 and said combustion chamber member will thus be locked in its lower operative position. When it is desired to raise the combustion chamber member above the wick tube member, the operator will turn said combustion chamber member in one direction so as to cause the lugs 21 to ride on the inclined edges 25 of the arms 24. When the lugs 21 shall have reached the upper ends of said inclined edges, a further turning movement of the cylindrical extension will cause said lugs to become disposed upon the horizontal seats 26 at the upper ends of the arms 24 and thus the combustion chamber member will be sustained in its elevated position. Engagement of the lugs 21 with the stop shoulders 28 will prevent the cylindrical extension from being turned too far. It is apparent that by turning the combustion chamber member in the reverse direction to that above described, the lugs 21 will be moved off of the horizontal seats 26 and when said lugs reach the inclined edges 25 of the arms 24:, the weight of the combustion chamber member will be suflicient to cause said lugs to ride down the inclined edges and enter the horizontal slots 29, thus causing the combustion chamber member to become disposed in operative position on the wick tube member and to be locked in such position.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is-

1. In a hydrocarbon burner, the combination with a wick tube member and. a combustion chamber member, of a cylindrical extension on one of said members provided with inwardly projecting lugs, and a plurality of arms fixed to the other member and having inclined edges and seats toreceive the inwardly projecting lugs of said cylindrical extension. 0

2. In a hydrocarbon burner, the combination with a wick tube member and a combustion chamber member, of a cylindrical extension depending from the combustion chamber member and guided within the wick tube member, said cylindrical extension provided with a plurality of inwardly projecting lugs, and a plurality of upright arms fixed within the wick tube member and each having an inclined edge and a seat at the upper end of said inclined edge for cooperation with the inwardly projecting lugs of the cylindrical extension for effecting the raising of the combustion chamber member and supporting the same in elevated position.

3. In a hydrocarbon burner, the combination with a wick tube member and a combustion chamber member, of a cylindrical extension on one of said members and adapted to enter the other member, said cylindrical extension provided with inwardly projecting lugs, a ring secured within said other member and having a plurality of arms, each of said arms having an inclined edge, a seat at the upper end of said inclined edge, a stop shoulder at one end of said seat, and a horizontal open slot adjacent to the lower end of the inclined edge of the adjacent arm.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
